How Well Does Your Browser Support HTML5?

Posted · Category: License Free, Tools

The HTML5 test score is an indication of how well your browser supports the upcoming HTML5 standard and related specifications. Despite these shortcomings they hope that by quantifying the level of support users and web developers will get an idea of how hard the browser manufacturers work on improving their browsers and the web as a development platform.

The HTML5 test score is calculated by testing for the many new features of HTML5. Each feature is worth one or more points. Apart from the main HTML5 specification and other specifications created the W3C HTML Working Group, this test also awards points for supporting related drafts and specifications.

Some of these specifications were initially part of HTML5, but are now further developed by other W3C working groups. WebGL is also part of this test despite not being developed by the W3C, because it extends the HTML5 canvas element with a 3d context.
